The indoor pool recommendation has a higher active chlorine level than you would need. Having even an hour or two of sunlight on the pool probably helps a lot in terms of UV breakdown of some organics (such as urea) and for airing out the pool for any volatile compounds. The minimum CYA would be 20 ppm though with your K-2006 test kit you can only easily measure down to 30 ppm so that would be the minimum.

So, 2 ppm FC with 20 ppm CYA or 3 ppm FC with 30 ppm CYA would be the minimum according to Ben's chart. However, note that your assumption that a lower FC results in lower absolute chlorine loss is wrong when a pool is exposed to a lot of sunlight. A pool with 8 ppm FC and 80 ppm CYA loses less chlorine than a pool with 3 ppm FC and 30 ppm CYA because CYA protects chlorine in a non-linear way shielding lower depths. However, in your situation with only 1-2 hours of sun, this effect may not be seen.

Also note that if you keep your water warm (88ºF), you may find a chlorine demand of 0.7 ppm FC per day even with no sunlight or bather load. So you want to make sure you have enough chlorine in the pool to not run out between your dosings. Having a higher FC and CYA gives you a larger chlorine buffer to protect you in case you miss a dose or when something unusual happens.
